Application filed. April 17, 1922. Serial No. 553,462.

This invention relates to a vehicle-buffer particularly designed andintended for use with motor vehicles, and a particular ob ect of theinvention is to provide a buffer which is attachable to the vehicle andrunmng gear frames above and below the ends of the frames. A furtherobject is to provide a number of independent adjustable bars with endconnecting means for combining them in a unitary impact member with alarge contact surface. Other objects will appear hereinafter. I

In the accompanying drawings, Figure 1 is a top view of a bufier with aplurality of parallel bars curved inwardly at the ends and the ends allconnected together;

Figure 2 is a rear view of this bufi'ertaken on the line 2-2 of Figure1;.

Figure 3 is a sectional view of the buffer showing the connection to thevehicle and running gear frames;

Figure 4 is a view of a hinged end connecting device as shown in Fi ure2; and

Figure 5 is another view 0 this end connector taken on the line 55 ofFigure 4.

In carrying out this invention, a pair of supports are connected at'theend of a vehicle, preferably by attaching one end ofeach support to thevehicle frame and the other end to the running gear frame with aprojecting vertical portion, as shown, for

example, in Figure v8, to which the buffer proper is connected.

A vehicle side frame 1 is supported from the running gear frame,represented by the axle 2 connected to the end of the side frame by theuppermost leaf of a leaf spring 3. A buifer member 63 in the form of aU-shaped resilient strip is connected on top of each- P side frame bymeans of a loop t with a hinge .plate 5, and the lower end of the member63- is connected by a loop 6 to a bolt 7 which'is supported by plates 40on each side of the spring 3 and clamped together over the top of thespring by a bolt -8. This provides a pair of spaced supporting members63 which extend a distance in advance of the vehicle frame where theyafford a support for a transverse buffer, the ends of which projectbeyond the members 63, the latter extending above and below the buffer.

A number of parallel bars 62 are mounted at the front of the sidesupport 63 by means of a clamping plate 64 which has a number offastening bolts 65 for separately clamping the bars in place. Theextremities of these parallel bars 62 are preferably rounded inwardlyand connected together by means of guard plates 66 against which the barextremities are held by clamping plates 67. Instead of a separateclamping plate, the guard may be formed, as shown in Figures 4 and 5, ofa'- two piece hinged guard 68 which is attached over the ends of thebars by means of clamping bolts 68.

In this construction itwillbe observed that the supporting basis is apair of buffer members, each substantially U-shaped with a verticalouter portion extending somedistance in advance of the end ofvthe sideframe vertical plane and separate ends attachable to the frame and gearabove and below the end thereof and at a distance back of the extremitythereof, and a plurality of bumper bars adjustably attached to thesupport on the vertical plane portion.

2, In a buffer, a pair of supports attachable at the end of a vehicleframe .and ex tending vertically in advance thereof, a plurality ofbumper bars mounted in the suports, and connecting means overlapping theends of the bars for joining them to ether.

3. In a buffer, a pair of supports for attachment at the ends of avehicle frame having a supporting portion in'a substantially verticalplane, bumper bars adjustable laterally in the supports, and meansenclosing the ends of the bars for connecting them together.

4. In a buffer of the class described, a pair of supports adapted to beattached at the ends of a vehicleframe and having spaced verticallyextending supporting portions, a plurality of bumper bars adjustable inand carried by the vertical supporting portions,

them together and mutually strengthening them,

,5. The combination .with a vehicle frame,

of a butler therefor, comprising a pair of {'6 supports adapted toproject vertically in front of the frame, a plurality of bumper barsextending across the supports, means for separately attaching the barsto the supports, and means attached adjacent the ends 1 of the bars toform a strengthening connection for the bars atthe ends thereof.

6. In a buffer of the class described, a plurality of buffer barsarranged in a substantially vertical plane, and vertically extend- .lngmeans covering the ends of the bars and secured. thereto, extendingtransversely thereof and separate from the buffer sup-- port to unitethe bars into a unitary impact member.
